That was the first version I tried. Looks good on the screen but I didn't like it very much when printed.

+1, semicolon should absolutely be used. Spacing is nice and all but even with proper spacing this is way too confusing otherwise.

@htorque: in French you would also add a thin space \, before the semi-colon. To my eye, it improves even further the readability of the formula, but depending on the language you're using, it might be against the rules.

+1 also from me. A semicolon should be used indeed.
